ABSTRACT:
This invention relates to a controller for a pumping installation using a combined pressure sensor and fluid level sensor arrangement. The controller includes a processor responsive to measurements from the sensor arrangement, as well as memory for storing a set of instructions for execution by the processor to correlate initial measurements taken by the sensors. The instructions allows the controller to monitor a fluid level in a well with the combined arrangement to compile a history of respective measurements for both sensors, and, in the event of an unexpected discrepancy between the measurements, to automatically calibrate the sensor arrangement according to the history of respective measurements to re-establish a correlation between the sensors.
